讀取 xml 節點值

Question

如何從 xml 文件下方讀取所有 ExportHeaderType 節點值。

<ArrayOfCEDataFileMappingSaveProp xmlns="http://schemas.datacontract.org/2004/07/Test.Models" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <CEDataFileMappingSaveProp>

嘗試以下操作：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication11
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlReader reader = XmlReader.Create(FILENAME);
            XmlSerializer serializer = new XmlSerializer(typeof(ArrayOfCEDataFileMappingSaveProp));
            ArrayOfCEDataFileMappingSaveProp array = (ArrayOfCEDataFileMappingSaveProp)serializer.Deserialize(reader);
          
        }
    }
    [XmlRoot(Namespace = "http://schemas.datacontract.org/2004/07/Test.Models")]
    public class ArrayOfCEDataFileMappingSaveProp
    {
        [XmlElement("CEDataFileMappingSaveProp")]
        public List<CEDataFileMappingSaveProp> saveProp { get; set; }
    }
    public class CEDataFileMappingSaveProp
    {
        public string DocAppTypeId { get; set; }
        public string DocTypeId { get; set; }
        public Boolean IsHeadingAvailable { get; set; }

        [XmlArray("HeaderTypes")]
        [XmlArrayItem("ExportHeaderType")]
        public List<HeaderTypes> headers { get; set; }
    }
    public class HeaderTypes
    {
        public string AppType { get; set; }
        public string DocType { get; set; }
        public string HeaderType { get; set; }
        public Boolean CheckboxField { get; set; }
        public int DataFileMapPK { get; set; }
        public Boolean IsHeaderRequired { get; set; }
        public Boolean IsHeaderTypeMandatory { get; set; }
        public int Sequence { get; set; }
    }

}

Answer 2

嘗試這個

XmlSerializer serializer = new XmlSerializer(typeof(ArrayOfCEDataFileMappingSaveProp));

ArrayOfCEDataFileMappingSaveProp result;
using (StringReader reader = new StringReader(xml))
result = (ArrayOfCEDataFileMappingSaveProp)serializer.Deserialize(reader);

List<ExportHeaderType> exportHeaderTypes = result.CEDataFileMappingSaveProp.Select(c => c.HeaderTypes.ExportHeaderType).ToList();

結果（json 格式）

[{"AppType":"LBX","DocType":"Batch","HeaderType":"Detail","CheckboxField":"true","DataFileMapPK":"4","IsHeaderRequired":"false","IsHeaderTypeMandatory":"true","Sequence":"0"},
{"AppType":"LBX","DocType":"Check","HeaderType":"Detail","CheckboxField":"true","DataFileMapPK":"4","IsHeaderRequired":"false","IsHeaderTypeMandatory":"true","Sequence":"0"}]
